How to read the result
Three numbers, three things to look at:
- Total impressions: the number of times your ad is expected to be seen across the campaign. Use this to size against your reach goal.
- Effective CPM: your cost per thousand impressions. Compare against the city's midpoint to know if you're getting average, premium, or discount inventory.
- Suggested screens: a rough count of how many screens this budget supports for the duration. Spread your buy across at least this many screens to avoid single-venue concentration.
What this estimator doesn't model
Three things real campaigns include that the estimator doesn't:
- Daypart targeting savings. Buying only your audience's window (lunch peak at retail, morning + evening at transit) saves 30-50% over always-on. The estimator assumes balanced full-day.
- Venue-mix premium / discount. Premium atrium LED costs 2-3× a roadside hoarding. Your real CPM depends on what you actually pick.
- Multi-city plans. Plan across multiple cities and the per-city CPM averages out. Browse all 25 cities.
